arious past studies defined GF as the promotion of economic, social, and environmental influences on financial services 
, with a general impact on the development of a sustainable economy and business 
. The term “green finance” is the combination of a set of three dimensions regarded as the “Triple Bottom Line,” comprising social, economic, and environmental aspects 
. Notably, most studies uniquely identify GF dimensions. However, only a few studies explore the connectivity of GF dimensions—social, economic, and environmental—in the context of banking sector 
. More recently, Zheng et al. 
examined the GF development in the Bangladeshi banking sector, particularly in private commercial banks (PCBs), and discovered that the level of awareness, beliefs, and understanding of the major dimensions of GF (social, economic, and environmental) and sources of green financing among PCB bankers were satisfactory for the successful implementation of GF in Bangladesh to facilitate the country’s long-term economic development. The study also identified the “economic dimension” as the most important dimension driving GF, followed by the “social” and then “environmental” dimensions. In addition, Rashid 
examined the impact of green financing by financial and non-financial sectors on the overall economic development of Bangladesh. The investigation revealed that the growth pattern of sustainable financing of the financial sector is marginal compared to the overall credit disbursed and remains below the threshold set by the Bangladesh bank. Although GF has huge prospects for the sustainable economic development of Bangladesh, financial institutions including banks have also identified some of the major challenges of its practices, which include the lack of policy formulation, lack of standardized guidelines for reporting, incorporation of environmental issues, etc. In another study 
, it was stated that the enforcement of clear guidelines by the Bangladesh Bank would result in the successful adoption of sustainable banking in Bangladeshi banks. The study also revealed that the lower growth of technological improvement, innovations of financial products, and a lack of social and ecological consciousness of the general community in the banking enterprises could constitute a hindrance to green growth. Therefore, GF can be said to play a crucial role in the improvement in banks’ sustainability performance through the financing of eco-friendly projects, and also the achievement of sustainable economic development of the country.
